To get Open PGP support we use GpgME >= 1.8.0. GpgME has now include Gpgme++ and QGpgME, that were living before in kdepim repositories.
GpgME gives us directly PGP and SMime support and needs gpg-agent, gpg2, gpgsm and a pinentry to be installed to work correctly. The package names differ between the distributions on Fedora the are named gnupg2, gnupg2-smime and pinentry-qt (there are several different flavours for diffrent environments. I think the Qt flavour matches best).
gnupg using ~/.gnupg as default homedir to store every file it uses. In our test docker environment, we setup all relevat files and added keys without passphrase to test PGP/SMime support. We also incuded one key
With Passphrase "test" <firstname.lastname@example.org>, that has a phassphrase named
You can get all keys with secret key available via
gpg2 --list-secret-keys all known keys with

Testing OpenPGP support
We have many testmails, that are signed and encrypted with keys without a passphrase.
All testmails can be found in the folder github:cmollekopf/docker.
openpgp-prefix are PGP/Mime messages RFC 3156.
openpgp-inline-prefix are PGP inline messages RFC 4880.
smime-prefix are SMIME messages RFC 2633.
To be able to also test gpg errors, we created some test mails, that triggers known issues:
openpgp-keymissing.mboxthis key is missing in the test environment, so gpg returns a KeyMissing error.
openpgp-wrong_passphrase.mbox, here a pinentry popups and if you press three time
Cancelin a row, a Passphrase error is returnd. If you enter the correct passphrase
testyou the the content of the mail. But than you need wither restart the testenvironment, kill
gpg-agentor simply wait 1h before you see the passphrase error again.
- you can unistall the
gnupg-smimepackage, or delete
/usr/bin/gpgsmby hand to trigger a UnknownError for smime encrypted messages. If delete all
gnupgp2related pacakges the application may react with segfaults.
We also have a unittest for gnupg errors in a lower level kde:kube/framework/domain/mimetreeparser/tests/gpgerrortest.cpp.
